METAL-WORKING- MACHINE.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed January 4, 1909. Serial No. 470,670.

. To all whom it may concern.'

Be it known that I, PATRrcK J. HAVEY, residing at Swissvale, in thecounty of Allegheny and State of Pennsylvania, a citi- Zen of the UnitedStates, have invented or discovered certain new and useful Improvementsin Metal-"Working Machines, of which improvements the following is aspecification.

The invention described herein relates to certain improvements inapparatus for upsetting a portion of the end o a pipe, spreading suchupset portion to a plane at right angles or approximately at rightangles with the axis of the pipe, thereby forming a flange and thenfacing such flange portion, said several steps forming parts of acontinuous operation.

The invention is hereinafter more fully described and claimed.

In the accompanying drawing forming a part of this specification Figure1 is a top plan view of my improved apparatus; Fig. 2 is a sectionalelevation on a plane indicated by the line II-II Fig. 1; Figs. 3 and 4are sectional views illustrating the construction of the chuck carryingthe parts directly operative on the pipe to effect the upsetting,iianging and facing operations; Fig. 5 is a sectional detail viewshowing the thrust bearing carrying the upsetting, flanging and facinghead, and other parts adj acent thereto; Figs. 6, 7 and 8 are detailedviews illustrating the several steps effected in the operation of myimproved machine.

In the practice of my invention, suitable means such as a fluid pressurecylinder l is secured to or in proper relation to guideways 2. A thrustblock 3 is secured by a bracket 4 to the end of the ram 5 of the fluidpressure cylinder and around this thrust block is arranged a sleeve 6engaging the thrust block as against any longitudinal movement relativethereto but free to rotate freely on the thrust block as hereinafterdescribed. The sleeve 6 is provided with lugs 6a adapted to engage lugs7 on the face plate 8 of a chuck carrying the tools operative on thepipe. This chuck as clearly shown in Fig. 3 is mounted in the sleeve 9provided with diametrically arranged lugs 10 and 11. One of these lugsis provided with an eye for the reception of a guide rod 12 while theopposite lug 11 is provided with a hook adapted to engage the oppositeguide rod 13. This construction permits of the turning of the chuck toone side for the insertion and removal of pipe. The pipe to be operatedon is held by clamping jaws 14 and 15 mounted on the rods 12 and 13, theupper section ofl the clamping jaws being weighted so that the uppersection will readily swing up out of the way when it is desired toinsert or remove the tube to be operated on.- A shaft 17 is so mountedin the ram 5 and thrust block 3 as to be capable of rotation andlongitudinal movement therein. This shaft is provided at one end with abeveled pinion 18 adapted to engage correspondingly shaped pinions inthe chuck as hereinafter described. This shaft has a pinion 19 mountedthereon, said pinion adapted to intermesh with a pinion 20, the latteralso intermeshing with a pinion 21, both pinions being carried by aswinging frame 22 loosely mounted on the shaft 17.

On a driven shaft 23 is mounted a gear wheel 24 which may be constantlyor intermittently driven andwhich will also intermesh with either one orthe other of the pinions 20 or 21. lBy swinging the frame so pinion 20will engage with gear wheel 24, the shaft 17 will be rotated in onedirection. When the frame 22 is swung so as to cause the pinion 21 toengage the gear wheel 24 a reverse rotation will be given to the shaft17 as the motion imparted to the pinion 21 is transmitted to the shaftthrough the pinions 20 and 19. The shifting of the frame 22 can beeffected in any suitable manner as for example by a lever 25 providedwith a suitable latch lever 25a, whereby it may be locked in either ofits positions. The thrust sleeve 6 is provided with a toothed rim 26engaging the gear wheel 27 on the shaft 23.

When it is desired to operate on the pipe which has been previouslyclamped in the jaws 14 and 15, the ram 5 of the cylinder 1 is caused tomove forward thereby pushing the end of the thrust sleeve 5 against theface plate 8 of the chuck and thrusting such chuck into operativerelation, as hereinafter described, with the end of the pipe. The bevelpinion 18 on shaft 17 engages when the shaft is shifted as hereinafterstated with the beveled pinions 29 on the ends of shafts 30 in thechuck. These shafts are provided at their outer ends with pinions 31intermeshing with pinions 32 on the threaded shafts 33. On these shaftsare mounted nuts 34 preferably having conical bosses or projections 35forming bearings for the rollers 36 which operate to upset and Y Yspread the end of the pipe. The nuts V34 are provided with.v lugs whichengage with and are held from-turning by guides 37 in the chuck. Theseseveral parts are so constructed and arranged that when the shaft 17 isrotated in one direction the nuts will be moved inwardly and when in theopposite direction will be moved outwardly e in a necessary it ispreferred that the rollers which are loosely mounted on the screwyshafts 33 should be held against the nuts by springs 3S so that theywill follow the nuts andbe in proper position when the latter areadjusted, and the sections held in operative relation to each other. Inways 39 arranged at right angles withV the ways 37 are mounted'blocks 40adapted to be shifted by the screws 41 to the desired position ashereinafter stated, and carrying rollers 42 loosely mounted on pinsprojecting from the blocks 40.

, The end of afpipe vhaving been properly heated, the pipe is placed inposition between theV jaws 14 and 15 with a desired lengthprojectingfrom the jaws 14. An

anvil ring 43 is then slipped over the projecting end of the pipe, andthe nuts 34 and lrollers 36 having been soadjusted relative to eachother and the diameter of the pipe,

that the neck or upsetting portion a of the rollers will bear upon theend of the pipe, the chuck is forced toward the pipe by the outwardmovement of the ram 5. The thrust sleeve is then rotated and with it thechuck so as to carry-the rollers around the end of the pipe. The chuckis moved forward to upset the portion of the pipe between the anvil ringwhich bears against vthe clamping jaws 14 and the rollers 36 by the ramof the cylinder 1. At the same time that therollers Yare adjusted asabove stated, the blocks 40 are also ,adjusted so that the rollers 42will hear against the inner periphery of the pipe during the upsettingoperation, so that. all the enlargement of the pipe during suchupsetting will occur outwardly. After the desired upsetting orthickening of the metal has been efected, the shaft 17 is shiftedlongitudinally so that the pinions 18V will engage the pinions V29 andthe frame 22 is swung so as to bring the pinion 20 into engagement withthe gear wheel 24. By the rotation of the shaft 17, the nuts 34 androllers 36 will be gradually moved outward, forcing the yconicalportions b of the rollers to operate on the previously thickened por-'tion of the pipe, and spread the thickened metal out radially to. forma Hange, the inward movement ofthe chuck against the pipe beingcontinued. By these conjoint movements the thickened portion of the pipe'ssaesi will be bent into the form of aV flange as Y shown inFig. 8. Inorder to face the flange thus formed cutting tools 44 are secured to thenuts 34 in such position that when Vthe nuts are moved outwardly asheretofore de scribed'these tools will be caused to traverse the outerface of the Hange formed on the end of the pipe.

After the completion of thepipe, the shaftY 17 is withdrawn and the ram5 with Ythe parts carried thereby retracted by anysuit` able means forexample anauXiliary Huid pressure cylinder '4G having its ram conf`nected by `rods 47 to lugs 4S on the head of the ram 5. i

By making therollers 36 in sections necks a of different lengths toYsuit the thickness to be produced in upsetting can be readily A placedin position, and the entire roller need not be replaced. The diskportion o of the rollers will serve as a stop by bearing against theanvil 43.

I claim herein as my invention 1. In a tool for Hanging pipe, a chuck i"y' provided with rollers, in combination with means for rotating thechuck, means for moving the chuck in the direction-ofthe Y length ofthepipe and thereby effecting an Y.

upsetting of the wall of the pipe adjacent to its ends by thej actionofthe rollers thereon the end of a pipe, means for adjusting the Y rollerstoward and from each other, and with adjustable rollers adapted yto bearagainst the inner periphery of the Ypipe in combina-tion with means formovingV the chuck in the direction of the length of the )i e means forrotatino` the chuck. and 1 C means for moving the interiorly operatingrollers to form the flange.

4. In a tool for HangingA pipe, a chuck provided with rollers adapted tobend the end wall outwardly to form a flange, cutters forV facing theHange and with means for moving the rollers and cutters outwardly duringthe rotation of the `chuckin combination with means for rotating thechuck. Y i
